The Physics of Sheet Sag Compensation in Large Furnaces
2026-02-15
When processing large sheets (up to $730 \times 800$) of PP or PET, one of the primary mechanical challenges is "sheet sag." As the material softens in the furnace, gravity pulls it downward, which can lead to uneven heating and contact with the heating tiles. Wenzhou Rayshape Machinery Co., Ltd., a subsidiary of the Elemotion Group, has engineered its Plastic Thermoforming Machine with a specialized "Sag Compensation" system within its four-stage heating furnace. This is achieved through a combination of precision air pressure support and high-speed servo feeding that maintains the perfect amount of tension on the sheet as it traverses the heating zones. Controlled by a real-time distributed digital dynamic temperature control system, the machine ensures that the thermal profile remains uniform despite the material's physical changes. The $\pm 1$°C tile accuracy ensures that no part of the sheet is under-heated, while the 3-minute rapid warm-up time ensures that production can begin efficiently. This attention to detail reflects the Elemotion spirit of mechanical excellence. Rayshape’s high-quality automated equipment is both energy-saving and hygienic, featuring an automatic counting and vertical stacking unit to handle the high-volume output of 45 molds per minute. Based at No. 19 Pinghai Avenue, Wenzhou, our seasoned R&D team provides professional after-sales service and a 90-set parameter memory to ensure standardized production for all our global clients. By solving the physics of sheet movement during the heating phase, Rayshape ensures a stable and reliable output, providing manufacturers with the professional and reliable machinery needed for high-spec, large-format plastic forming applications. Our machines are a leading choice for those who demand precision and durability in their industrial production lines.
